Why are women much more likely to tear their ACL during menstruation?

Dr. Michael Roizen, MD
Internal Medicine

These days, it's not just football players and skiers who are tearing their ACL knee ligament. A lot of people are doing it - and menstruating women are doing it eight times more often than other people. Why? During menstruation, hormones cause the soft tissue to become like a wet rubber band - and thus more likely to rupture. In order to keep pressure off the ligaments, it's important to build muscle around the knee (like in the quadriceps), so your muscles - and not the joint - can take on some of the force that you'll experience, be it through sports activity, or tripping on a curb.
